He made a 999 call to say he had killed his wife and he was arrested in the car park, the force said.

'Lost self-control'

Singh was found with a large kitchen knife in his jacket and with blood on his hands.

A post mortem examination revealed that Mrs Kaur suffered a fatal wound to the neck after being stabbed three times.

Police said Singh, who admitted killing his 40-year-old wife to a friend, had denied murder, claiming he had lost his self-control after his wife had taunted him about his sexual prowess - a claim later rejected by the trial judge.
